DXCoreAdapterMemoryBudget structure (dxcore_interface.h)
Describes the memory budget for an adapter.
Syntax
struct DXCoreAdapterMemoryBudget {
uint64_t budget;
uint64_t currentUsage;
uint64_t availableForReservation;
uint64_t currentReservation;
};
Members
budget
Type: uint64_t
Specifies the OS-provided adapter memory budget, in bytes, that your application should target. If currentUsage is greater than budget, then your application may incur stuttering or performance penalties due to background activity by the OS, which is intended to provide other applications with a fair usage of adapter memory.
currentUsage
Type: uint64_t
Specifies your application's current adapter memory usage, in bytes.
availableForReservation
Type: uint64_t
Specifies the amount of adapter memory, in bytes, that your application has available for reservation. To reserve this adapter memory, your application should call IDXCoreAdapter::SetState with state set to DXCoreAdapterState::AdapterMemoryBudget.
currentReservation
Type: uint64_t
Specifies the amount of adapter memory, in bytes, that is reserved by your application. The OS uses the reservation as a hint to determine your application's minimum working set. Your application should attempt to ensure that its adapter memory usage can be trimmed to meet this requirement.
